Abstract

To provide a technique of reducing the costs for maintenance work and also the downtime of products. There is provided a maintenance system that calculates a timing to make a visit for maintenance work for consumable parts of a machine to be maintained. The maintenance system includes: a visit-interval calculating section for calculating a visit interval to make a visit for maintenance work for each consumable part on the basis of a failure rate distribution; a replacement-interval calculating section for calculating a replacement interval to replace the consumable parts for each consumable part on the basis of the failure rate distribution; and a visit-timing calculating section for calculating a timing to actually visit the machine to be maintained on the basis of the visit interval calculated by the visit-interval calculating section and the replacement interval calculated by the replacement-interval calculating section.
